We would like to let everyone know that Spelling Plus Library (aka SPL), our Flash/Flex spell-checking library has been released open source.

We first released SPL as a commercial component over 6 years ago, with a major overhaul to support the Text Layout Framework almost 4 years later. It was always our goal to provide a high quality, performant, and feature rich product, backed by great support. As the requirements of the industry have shifted, and the demand for Flash components has dropped, we felt it was a great time to release it to the community at large.

The entire SPL repository is now available under an MIT license, meaning it is free to use for everyone, including on commercial projects. This includes:

The Flex-based AIR application that helps create, modify, and export word lists

All examples, spikes we used for testing, and some internal demos

The build process to export Flash and Flex SWCs

Generated word lists using custom compression for US and UK English, along with tested word lists for Spanish, French, and German.

You can check out the GitHub repository to get everything. Feel free to submit pull requests. Please note that we are no longer supporting SPL, so any questions or issues reported may not get immediate responses.

Thanks to our supporters over the years, we are super proud of what SPL has accomplished, and hope that it will continue to see life moving forward.
